Crisp facial markings make the White-throated Sparrow an attractive bird as well as a hopping, flying anatomy lesson. There’s the black eyestripe, the white crown and supercilium, the yellow lores, the white throat bordered by a black whisker, or malar stripe. They’re also a great entrée into the world of birdsong, with their pretty, wavering whistle ofOh-sweet-canada. These forest sparrows breed mostly across Canada, but they’re familiar winter birds across most of eastern and southern North America and California.
Although they look nothing alike and aren’t particularly closely related, the White-throated Sparrow and the Dark-eyed Junco occasionally mate and produce hybrids. The resulting offspring look like grayish, dully marked White-throated Sparrows with white outer tail feathers. White-throated Sparrows typically nest on or near the ground. Occasional nests are built up to 15 feet off the ground in conifers. Usually, these nests are second attempts after a pair has had a ground nest robbed by a predator.
